Hi Thomas Kell ,

I noticed your post is related to Sage 50 US, and it appears you're encountering issues with GL accounts when changing vendors on purchase orders. To help you resolve this, I'm going to provide the steps to update the default account on a vendor's profile, as this might be affecting the GL account selection:

1. Go to the 'Maintain' menu, then choose 'Vendors…'.
2. Enter the unique ID for the Vendor you wish to update.
3. In the vendor record, navigate to the 'Expense Account' field.
4. Select the appropriate GL account you want as the default for this vendor.
5. Make sure to consult with your CPA before using a different account type if you're unsure.
6. Save the changes to the vendor record.

For more detailed guidance, you can refer to these articles:
- How do I create a new vendor?
- General ledger (GL) account field is missing on task windows

After you've made these updates, the item number for a stock item should retain the correct GL account regardless of vendor changes.

To ensure that other users of Sage 50 US can benefit from this information, I will move this post to the Sage 50 US Support Group.

Thanks,
Erzsi
